Not that there are any unofficial ones

WE’RE NOT FROM HERE

WE’RE NOT FROM HERE is the story of a family of humans who immigrate to an alien planet after Earth is destroyed in a nuclear war…only to discover that the aliens who invited them have changed their minds about opening their society to a species that just blew up its own planet.

It’s funny, scary, entertaining, and has a lot to say (metaphorically) about real-world debates over immigration and refugees.
